Abstract: A combination of a furnace filter and a scented evaporant packet inserted in a cut out portion of the filter. The evaporant is contained and wrapped in foil when not in use. Upon partial or entire removal of the foil by a tear tab, the evaporant is exposed to the air flowing in the cold air duct of a furnace--Such as used in dwellings, thereby the entire house may be scented. The secondary purpose of the evaporant is to give an indication of when the filter has to be replaced. This will occur when the scent is no longer evident in the air.
